New to site, but visit quite often. Never left here without learning something. I have a 2005 ford E350 with a 6.0. Supposedly truck has reman at about 18000. on it. Stopped running, no restart. Did air test, found STC blown. New style STC, but put in wrong, (crooked). Replaced STC, re airtest, passed. Road test and tow back, shut down while driving. Test for codes. Codes for cam, crank and EGR opens. (Using Snap-On Solus Pro) Found faults in harness and repaired. Also popped EGR, no leak noted, and actually looks new. After electricl repair, road test and tow back, shut down with no restart. Got it running,re air test, thought I might have missed something, no leaking noted, but now throwing same codes for cam and crank sensor opens. Havent popped valve covers to look at stand tubes or dummy plugs yet. Any thoughts?

I can't help with your codes and have no idea what the 'air test or STC' are... but I do know that my '04 E350 died after I went over a snowbank at the end of the driveway several yrs ago, with about 100+k on the clock and had it towed to a dealer and they found a chaffed wire shorting in the wire harness on the steering wheel harness going down thru the floorboards or where ever it goes.
The mechanic told me it was a common problem in ambulances and vans, said the harness was made slightly too short... just short enough to over time chafe and short.
They spliced the wires and never had a problem since.
Again not sure if this helps... but it saved my van

You said it set both CMP and CKP codes. It will set CKP for extended cranking, but not CMP. Start by tracking down the cam sensor code. Your SOLUS should allow for injector BUZZ test, try that and see if the injectors are firing. Reply with some PID's like injector control pressure , cam sync, and FICM voltages.
